html - jQuery Mobile: Get data passed to page via changePage

I'm trying to pass an object from one page to another and accoriding the JQM docs this should be correct:

$.mobile.changePage( "about/us.html", { data: {paramUno:"Uno", paramDos:11} });

My problem is that I'm not sure of the best way to access those values once us.html has loaded. I added page event callbacks for pageshow, pagebeforeshow, pageinit, and pagechange and in every case, event.data is undefined. Whats the proper way to do this? I'd prefer to not use localStorage or a global/namespaced var unless that's my only choice.

Thank you!

Solution

Send them like this:

$.mobile.changePage('page2.html', { dataUrl : "page2.html?parameter=123", data : { 'paremeter' : '123' }, reloadPage : true, changeHash : true });

And read them like this:

$("#index").live('pagebeforeshow', function (event, data) {
    var parameters = $(this).data("url").split("?")[1];;
    parameter = parameters.replace("parameter=","");  
    alert(parameter);    
});

More examples can be found here: jQuery Mobile: document ready vs page events, just look for chapter: Data/Parameters manipulation between page transitions.

Example:

index.html

<!DOCTYPE html>
  <html>
    <head>
    <meta charset="utf-8" />
    <meta name="viewport" content="widdiv=device-widdiv, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
    <meta name="apple-mobile-web-app-capable" content="yes" />
    <meta name="apple-mobile-web-app-status-bar-style" content="black" />
    <title>
    </title>
    <link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
    <script src="http://www.dragan-gaic.info/js/jquery-1.8.2.min.js">
    </script>
    <script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>  
    <script>
        $(document).on('pagebeforeshow', "#index",function () {
            $(document).on('click', "#changePage",function () {     
                $.mobile.changePage('second.html', { dataUrl : "second.html?paremeter=123", data : { 'paremeter' : '123' }, reloadPage : false, changeHash : true });
            }); 
        }); 

        $(document).on('pagebeforeshow', "#second",function () {
            var parameters = $(this).data("url").split("?")[1];;
            parameter = parameters.replace("parameter=","");  
            alert(parameter);
        });         
    </script>
   </head>
   <body>
    <!-- Home -->
    <div data-role="page" id="index">
        <div data-role="header">
            <h3>
                First Page
            </h3>
        </div>
        <div data-role="content">
          <a data-role="button" id="changePage">Test</a>
        </div> <!--content-->
    </div><!--page-->

  </body>
</html>

second.html

<!DOCTYPE html>
  <html>
    <head>

    <meta name="viewport" content="widdiv=device-widdiv, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />

    <script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>  
   </head>
   <body>
    <!-- Home -->
    <div data-role="page" id="second">
